What is possible? I know for sure that these are from a 1530 / 1570 except maybe the last one. What I am asking is if there's anyone able to identify the single parts refs.

If you number the pictures, I may be able to name them. On my phone it's hard to go back and forth.

Without seeing them properly, on scale, I am making my best guesses here.

1) Screws for automatic device lower bridge #7905
2) I don't recognize these screws, but they may be for the bridles #166
3) Screw for pallet bridge #7845
4) Screw for friction spring #7840
5) Screw for train wheel bridge, short #7854
6) Screw for crown wheel core #7875
